The wick is made of a high grade of cotton or linen. The material is woven (or braided) so that it will burn in one direction and will curl so that its end remains in the candle flame's oxidizing zone for even and intense burning. Often, wire-core wicks are used.
Differentiate among the non-urinary waste management systems. The excretory system is a passive biological system that removes excess and unnecessary materials from the body, so as to help maintain homeostasis and prevent damage. The main organs involved in waste management are the skin, lungs, liver, and kidneys.
The small intestine takes all the nutrients it needs from the food. Then, all the rest of the food travels down the large intestine and out the other end. The bowel has the j â¦ ob of recovering water from the waste food. Metabolite waste and by-products are removed from the blood by the kidneys. The CO2 is removed from the lungs by breathing. There are a few other waste processes such as excess heat removed by radiation and sweating.
